Installing the Ethernet Ports
This chapter covers how to install the Ethernet portion of the ITI-8241C-S
CompactPCI
®
Combination adapter in your system and how to verify that the
Ethernet ports have been installed correctly.
Refer to section “Installing the IntraServer CompactPCI Host Adapter” to
install the combination adapter in your CompactPCI
®
machine.
Ethernet 10/100 Auto-Negotiation
The qfe Ethernet interface used on the IntraServer ITI-8241C-S adapter
supports auto-negotiation. The auto-negotiation protocol, as specified in the
100BASE-T standard, automatically selects the operation mode (half-duplex
or full-duplex) and speed (10Mbps or 100Mbps) based on the network the
adapter is on.
The link speed and modes supported by the IntraServer ITI-8241C-S adapter
are listed below in order of decreasing priority:
•
100Mbps, full-duplex
•
100Mbps, half-duplex
•
10Mbps, full-duplex
•
10Mbps, half-duplex
When the system is booted, the IntraServer CompactPCI
®
adapter advertises
these capabilities to the Link Partner at the other end of the link (a hub,
switch, or another network interface card (NIC) in a host system). If the Link
Partner also supports auto-negotiation, it will advertise its capabilities over
the link, the common highest priority mode supported by both sides will be
selected automatically for the link operation.
If the IntraServer CompactPCI
®
adapter is connected to a remote system or to
an interface that is capable of auto-negotiation, your system will
automatically select the speed and duplex mode.
If the IntraServer CompactPCI
®
adapter is connected to a Link Partner in
which auto-negotiation protocol is not operational, you can configure the
device to not use this protocol and force the driver to set up the link in the
mode and speed of your choice.
Refer to the Platform Notes; “The qfe Ethernet Device Driver” document for
mode information on the qfe driver and auto-negotiation. This document is
also available in the Solaris™ AnswerBook.
